Thermal Components Boost Performance of HVA C Systems

According to results from independent laboratory
testing, filters treated by PuraClean provided an improvement
in filtration efficiency ranging from 200 percent
when exposed to 3 micrometer particles, to more than
1,200 percent when exposed to 7 micrometer particles
such as pollen, dust, and dirt. Test results also indicated
that PuraClean caused no measurable difference in resistance
to airflow. Mainstream says that, unlike other filter
sprays, PuraClean can actually make filters more efficient
because air conditioner evaporator coils stay cleaner and
provide improved energy efficiency.

Available to service technicians from HVAC suppliers,
Mainstream has sold
between 7,000 and 8,000
bottles of the product
since 2007, but expects
those numbers to drastically
grow in the near future.
Currently, the product is being
reviewed by the Asthma and
Allergy Friendly Certification
Program to become a certified
residential allergy- and asthmareducing
HVAC product.
“Mainstream Engineering
is working hard at making
this NASA-developed
technology available to
every consumer,” says
Scheckel.

Much like PuraClean,
Scheckel says the development
of the QwikShot
acid flush product took place after research and development
under a NASA SBIR. “We worked on exacting the
formulation and wanted to make it as safe and easy to use
as possible,” he says. “QwikShot improves the thermal
stability of air conditioning and refrigeration systems
and extends the life of the system by removing systemdestroying
acids from the thermal circuit.”

Used for vaporizing acid and moisture when it occurs
in air conditioning and refrigeration systems, QwikShot is
injected into a system during operation. After it is introduced,
the product vaporizes with refrigerant and travels
throughout the system to chemically attach to acid and
moisture molecules. It then flushes the molecules to the
filter or drier. Unlike acid neutralizers that leave a saltbased
residue from a chemical reaction, QwikShot leaves
no residue in the system.

“Traditional techniques require the technician to
open the system and neutralize compressor oil by opening
up the compressor, or a line set near the compressor, and
add the neutralizing product, says Scheckel. QwikShot is
simply introduced into the compressor oil.

According to Mainstream, over 75,000 applications
of QwikShot have been sold. “HVAC and refrigeration
service technicians who fix residential and commercial air
conditioning systems use QwikShot to treat systems with
signs of acid prior to system failure, and it improves the
thermal stability,” Scheckel says.

Due to the research and development opportunities
provided through NASA’s SBIR program, Mainstream
has significantly improved the normal operation of
HVAC systems on Earth.
